CMV IgG seropositivity, absolute IgG titers, and levels of neopterin and IFN-γ of all subjects and by CMV DNA detection status

Study variables	All participants (N=71)	CMV DNA (+)(N=30)	CMV DNA (−) (N=41)	P Values
CMV seropositivity, %	73.2%	100%	53.7%	.01
Absolute CMV IgG titer (EU/ml), median (range)	40.6 (0.9–71.4)	42.5 (0.9–71.4)	39.1 (0.9–65.9)	.23^*
Neopterin (nM), mean±SD	9.1±3.4	10.6±4.4	8.0±1.9	< .0001
IFN-γ (pg/ml), median (range)	1.09 (0.40 – 10.37)	1.09 (0.43 – 5.20)	1.09 (0.40 – 10.37)	.77^*

These P values were obtained from Mann-Whitney test.
